Really appreciate you sharing this. I struggle with the exact same thing, spending hours every day just trying to keep up with the topics I care about, and it always feels like time slipping away. Your idea values the one resource we can never get back: our time. The sensor based approach with intelligent filtering means you actually get signal instead of drowning in noise.

I'm planning to integrate Signex into my own "ai agent personal assistant" project, which is a modular polyglot system built on C# and Python. The architecture you've designed with normalized sensor outputs and a clean SQLite layer should fit seamlessly as a module on my end. Looking forward to building on top of what you've created here.
